Kace System Deployment throw "Could not ping Appliance" when trying to boot to it on IPV4

We have been using this appliance since January without any issue, but with these new systems, we suddenly get this error message. I strongly imagine it has to do with NIC drivers since I can't get a Mac address, since it usually prints out on the screen when deploying, and running IPConfig returns me nothing, meaning the device clearly isn't able to communicate with the appliance.

I have tried to research this for quite some time now, and can't seem to find any post about something like this...

How would we be able to get the drivers in order for the device to deploy properly?
